Yamaha Outboard Model Numbers - Service Manual

[pmarker58]

I am trying to buy a Service Manual for a 2001 Yamaha 50HP 4 Stroke, model number F50TRLA. When I go on the Yamaha website it only shows model number F50TRLZ and the Service Manual is LIT-18616-02-33. I also saw service manuals on ebay for a F50A,F50B, F50X, F50Z. What is the difference between the F50A, F50B, F50Z models. I just trying to figure out if the LIT-18616-02-33 is the correct service manual I should be buying.

An F50TLRA is a 2002 model year motor. An F50TLRZ is a 2001 model year motor.

The last letter indicates the year. After the letter Z in 2001 they went back around to the start of the alphabet for the letter A. An F50B as in F50TLRB would be a 2003 model year motor.

Very little differences between model years on carburetted F50's. The same service manual (LIT-18616-02-33) is used for both a 2001 F50TLRZ and a 2002 F50TLRA motor.
